River channel flood prevention device for river channel repair and protection engineering and flood prevention method of river channel flood prevention device
The invention relates to the technical field of river channel repair and protection engineering, in particular to a river channel flood prevention device for river channel repair and protection engineering, which comprises a filter screen arranged between two river channels and flood prevention cloth connected with the filter screen, a switching mechanism is arranged between the filter screen and the flood prevention cloth, and the switching mechanism is provided with an unwinding roller and a winding roller. One side of the flood prevention cloth is connected with the unwinding roller, one side of the filter screen is connected with the winding roller, a guide roller is further arranged at the joint of the filter screen and the flood prevention cloth, and a supporting mechanism is further arranged between the two river channels and on the back side facing the upstream face of the filter screen. And the flow speed can be slowed down under the condition that the river is torrential, the flood control effect is improved, the river is kept clean, and garbage flowing along with the river is reduced. The invention further relates to a riverway flood prevention method for the riverway repair and protection project.
本发明涉及河道修防工程技术领域，具体是涉及一种河道修防工程用河道防汛装置，包括设置在两个河道之间的滤网，防汛装置还包括与滤网连接的防汛布，滤网和防汛布之间设有切换机构，切换机构设有放卷辊和收卷辊，防汛布的一边与放卷辊连接，滤网的一边与收卷辊连接，滤网和防汛布的连接处还设有导向辊，两个河道之间且朝向滤网迎水面的背侧还设有支撑机构，本发明通过滤网和防汛布之间来回切换的方式，保证河流正常情况下能够正常的流动，也保证了河流湍急的情况下能够减缓流速，提高了防洪效果，也保持了河流的清洁，减少垃圾随着河流的流动。本发明还涉及一种河道修防工程用河道防汛方法。
